What types of books do they provide or are they Ebooks? Are the books decent for use as reference material later on and after the classes are over? I'm pretty sure i have more questions just cant think of them as of now.

To answers both of those questions they haven't provided any ebooks for the classes I've taken. The books I received for the major classes have only been used for my own reference and I have not been required to read them. I'm not quite sure how great of a reference they will be after my classes are over but there definitely nice to have.
